我正在尝试运行一个使用imgaug软件包的模型，我有一行代码可以
from imgaug import augmenters as iaa.
当我输入pip install imgaug行时，我相信我已经像命令提示符中一样成功安装了imagaug，我收到以下消息：
Requirement already satisfied: imgaug in c:\python36\lib\site-packages

imgaug) (1.1.0)

Requirement already satisfied: decorator>=4.3.0 in c:\python36\lib\site-
packages (from networkx>=1.8->scikit-image>=0.11.0->imgaug) (4.3.0)
但是，当我在Jupyter Notebook中运行代码时，出现错误消息
ModuleNotFoundError: No module named 'imgaug'.
此错误的原因是什么？我是否必须在特定环境中安装或运行imgaug？我正在使用Windows，所以sudo pip安装将无法进行。非常感谢您的关注和帮助。
